Wonder if anyone has direct experience with the Crumpler Karachi Outpost backpack and a pro body like a 1D Mark IV or a gripped 5D Mark III. Saw one in a store in San Francisco and that is what the clerk recommended but didn't have my camera with me to check it out.
From their website it look like the Large size is recommended.
If you have pictures to share that would be great.
